Using PHP Selector Without Breaking Applications

CloudLinux PHP Selector can improve flexibility, but unplanned version or extension changes can break production applications quickly.

Safe Change Process

• Confirm the required PHP version from the application or vendor documentation.
• Enable only the extensions that are actually required.
• Test after each major change instead of applying multiple changes at once.
• Keep a note of the previous configuration so rollback is immediate.

Support Tip

When an application fails after a version change, compare the module set as well as the version number. Missing extensions are a frequent cause of incomplete recovery.
